For comparison, Microsoft's Windows 7 - which was released in Oct. 2009 - had 1.47 percent of the OS market by the end of 2009 and 14.46 percent by the end of 2010, according to Net Apps.

On the browser front, meanwhile, Microsoft's IE is still on top. According to Net Apps, IE8 remains in the top spot, though IE10 is expected to break through in the next couple of months, thanks to its introduction on Windows 7.

Version 8 made up 22.67 percent of the market-share pie last month, while IE10 is crept up to 13.52 percent  10 months after its initial release. Mozilla Firefox 21 and Google Chrome 27 are holding their own, as well, boasting 12.47 percent and 13.76 percent, respectively. Apple's Safari, meanwhile, accounts for only 3.27 percent of users; other browsers collectively take 16.48 percent.
